TNS01
THERMAL NEEDLE SET FOR
THERMAL RESISTIVITY/ CONDUCTIVITY MEASUREMENT
The TNS01 Thermal Needle Set
allows performing fast measurements of the thermal resistivity or
conductivity of soils with optimal flexibility. The measurement complies
with IEEE Standard 442-1981 as well as with ASTM D 5334-92 Standard The
system includes two different needles for use in the laboratory as well as
on site. It is suggested to also consult the brochures of components FTN and
MTN, as well as TPSYS, which is more accurate but has less robust needles.
Figure 1. TNS01 in operation. The
Non-Steady-State Probe TP07 (1), mounted on the Insertion Tool (IT02) (2),
is inserted into the soil sample. The user performs control and read out of
the experiment from the CRU01 (3), using its keyboard and LCD. The CRU01
contains a rechargeable battery pack for powering the TP07. The measurement
result is immediately generated.
Figure 2. TNS01 in operation.
The Non-Steady-State Probe TP09 (1), mounted on the Lance (LN01) (2), is
inserted into the soil. This configuration is typically used for
measurements around the typical depth of burial of high voltage cables, more
than 1 meter depth in the field. The same CRU is used.

TNS01 essentially consists of a combination of
FTN and MTN components: the insertion tool IT02 and needle TP07 of MTN are
added to FTN.
NEW!
- For high accuracy calibration CRC
Calibration Reference Cylinders are available.
- For insertion into hard soils GT
Series Guiding tubes can be applied for needle type TP07.
